ROLLERTBEIABING.

Specification o Letter-slate. I Iffitentd Mar, 19,1912.

Application filed 1121117, 1907, Serial No. 374,305. Renewed 1911. Serial No, W320.

To all whom it may concern:

Be it known that I, Emms'r J. TAYLOR, a

citizen of the United States, resid' at Highlandville, in the county of Norfo k and State of Massachusetts, have invented new' and useful Improvements in Roller-Bearings, of which the following is a specification.

This invention relates to roller bearings for shafting, the object of the invention being to provide an anti-friction bearing for shafting, whether the same is used in connection with a parallel line of shafting or whether the same may be used in connect-ion with shafting to which an end thrust is applied.

The object of the invention is further to provide a bearing of the character set forth which eliminates sliding friction by means of rollers so arranged with relation to'each other that they roll on the parts with which they contact.

The invention consists, in a roller bearing, of the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof. 1

Referring to the drawings: Figure 1 is a side elevation of my improved roller bearing. Fig. 2 is a plan View of the'same. Fig. 3 is a sectional elevation taken on line A-A of Fig. 1. Fig. 4 is ajsectional elevation taken on line B-B of Fig. 2.

'Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 is a sleeve adapted to be fastened to a shaft.

6, 6 are supporting rollers arranged'in series, each of said rollers having an annular groove 7 therein, preferably midway between the opposite ends thereof. The opposite ends of the rollers 6 have oppositely inclined conical ends 8, 9 which bear against corresponding conical faces 10,-11 formed upon the bearing rings 12, 13 and 14, 15, respectively. The bearingrings 12 and 14 are mounted upon the sleeve 5 and the bearing rings 13 and 15 are mounted within a hollow cylindrical casing 16. Said bearing rings 13 and 15 are internally beveled and contact with an inner circumferential surface within said casing 16. The bearin ring 12 rests against a shoulder formed upon the periphery of the sleeve 5, while the bearing ring 13 rests against a shoulder formed within the casing 16.

The bearing ri a 14 is adjusted longitudinally of the sle e 5. in order to bring its conical face in contact with one conical end of the supporting rollers 6 by a. collar 17 which has screw-threaded engagement with said sleeve and bears against the bearing ring 14, said collar 17 constituting a lock to from moving longitudinally in one direction within the casi 16.

A felt washer 19 is clamped to the outer face of the plate 18 by a washer 20 and screws 21. The opposite end of the casing 16 from that to which the plate 18 is attached has a cover plate 22 which hasscrewthreaded engagement therewith and has attached thereto a felt washer 23 by means of screws 24 and a washer 25. The felt washers '19 and 23 serve to keep the dust from entering the interior of the bearing.

Separating rolls 26, 26 are arranged in pairs. each pair of said rolls being inolosed .within a retaining ring 27, which projects nto the annular grooves 7, 7 in the supporting rolls 6 adjacent thereto. Each of the separating rolls is provided with two annular ribs 28,28. These annular ribs are preferably beveled or conical upon their op posite sides, thus forming inner beveled shoulders 30, 30 and outer beveled shoulders 31,31 upon the peripheries of said separating rolls. The inner beveled shoulders 30 bear against corresponding conical or beveled surfaces formed upon the inner edges of the rings 27, and thus keep said rings out of contact with the, supporting rolls 6. The outer beveled shoulders 31, 31 bear against beveled edges 32 upon the supporting rolls 6, saidb'eveled edges'bein'g adjacent to the annular grooves 7 in said supporting rolls. 'It will thus be seen that the double beveled shoulders or ribs 28, 2%prevent the separating rolls from moving origitudinally of the bearingrelatively to'the separating rolls.

i of said pairs of separating rollers between nular grooves provided in said adjacent sup- Lto bear against the opposite side porting rollers and also between the separat- -.to secure is:

supporting rollers each having oppositely 35- conical peripheries, and means to adjust said tween each pair of adjacent supporting roll- In operation the casing may revolve about the shaft or the shaft may revolve within 5 thecasing. Assuming the latter to be the fact and that the shaft with the-sleeve 5 attached thereto-rotates in the direction of the arrow a (Fig. 3), the supporting rolls 5 will rotate in the direction of the arrow b-l (Fig. 3) while the separating rolls will rotate in the direction of the arrows thereon. 1 Thus, it will be seen that a rolling'friction takes place between the bearing rings 12 and 14 and the supporting rolls 6; also that i a rolling friction takes place between the Supporting rolls 6 andthe bearing rings 13 and 15 and that a rolling friction takes" place between the separating rolls and suping rolls and their retaining-rings Having thus described my invention, what I clalm and desire by Letters Patent 1.
